Frequently asked questions
How does the 90-day plan work?
Each day focuses on a single food group — protein, starch, carbs, vitamins or a water day. This food-dissociation rhythm helps your body lose weight steadily. Just open the app each morning and follow that day's guidance and recipes.
Is the app free?
Yes. The full 90-day plan, recipe library, automatic grocery list and weight log are free. Premium adds a personalized plan, meal swaps, advanced tracking, data export, a maintenance plan and removes ads.
How do I manage or cancel my Premium subscription?
Subscriptions are billed through Google Play or the App Store. Manage or cancel any time in Google Play → Subscriptions or App Store → your name → Subscriptions. Cancelling stops future renewals; you keep Premium until the current period ends.
How do I move my data to a new phone?
Sign in with the same account (email, Google or Apple) on your new device and your plan, weight history and preferences sync automatically. If anything's missing, email us and we'll help restore it.
How do I export or delete my data?
Premium members can export their weight and progress history from Settings. To permanently delete your account and all your data, use our account deletion page, or email us and we'll take care of it.
Can I follow the plan with dietary restrictions?
Yes. Premium personalization adapts the plan to vegetarian, no-dairy and allergy needs, and lets you swap individual meals while keeping the plan on track.
